    Hi guys,

    I have new, unused plastic bio balls for sale, the kind used as filter media.

    I am looking at R75.00 per kg, which is approximately 110 balls. (this may vary as I am selling according to weight not quantity)

    I bought a fairly large amount, and I'm not going to use everything so you are welcome to take more than 1 kg at a time. I will ship them in 1kg bags.

    Please see pictures below.

    Do the balls float or sink?
    Sorry if it just sounds wrong. But that is my question. I prefer the floating type. A lot easier to siphon detritus under it out.

    This can only float, to light to sink...

    In my quarantine holding tank I do have bioballs. Different types and some sink and some float.

    Hi guys,

    I have decided to drop the price to R75.00 per 1 kg.

    Hi @RiaanP and @Express Reef,

    The balls seem to just sink in fresh (tap) water and seem to just float in sea water, so I am guessing the density must be around 1.01 g.cm−3
